PS VITA = UNDERRATED! But in my case, I'm playing VITA games on the PSTV.
I cannot describe it, but there is something very progressively novel about the playing VITA games on a big screen televison. And it's amazing that you can get so much out of a small plastic box that's just bigger than the size of a cellphone. Of course I'm taking about the entrie experience of a "miniaturized" console, projected on a big screen, sitting back on a nice couch, Dual Shock 3 in hand and with ambient lighting behind me. But my gaming tastes on the VITA are not mainstream since I believe the main attractions are the niche JRPG like titles.
So finally to my main point, I bought Xblaze Code: Embryo, Xblaze Lost: Memories and Tokyo Twilight Ghost Hunters all for the... PS3! But I wondered if I should have gotten those for the VITA instead since all three of those titles are virtually the same between the VITA and the PS3. One, it helps support VITA sales. Two, the cases take up less space on shelves. And three, I like seeing the round icon of the corresponding games on the VITA/PSTV desktop. I did buy The Legend of Heroes: Trails of Cold Steel for the PS3, but I did read that it is the better looking verison so I'm cool with that.
Well, that's sort of my "hindsight" rant about my more recent game purchases. Anyone want to trade their VITA versions for my PS3 versions? ;)
